Mechanism and Clinical Significance of AF Pedicle Screw System in the Treatment of Thoracolumbar Fractures

目的探讨AF椎弓根螺钉系统治疗胸腰椎骨折的机理及临床意义。方法选取经CT确诊的胸腰段骨折患者41例,对其使用AF系统复位固定,观察其临床效果,总结其临床意义。结果本组患者经治疗后仅14例患者出现不同程度胸腰椎部疼痛,4例患者椎体前缘高度出现小幅度丢失,其余患者预后情况良好,未出现神经根相关损伤。结论行AF系统时胸腰段患者进行复位固定治疗的临床效果较为突出,患者预后情况较好,复位更加精确,在调整畸形方面起重要作用,值得推广于临床实践中。

[ ABSTRACT] Objective To discuss and analyze the mechanism and clinical significance of AF pedicle screw system in the treat -ment of thoracolumbar fractures .Methods Forty-one cases from thoracolumbar fracture patients who were diagnosed of CT were selected , fixed with AF system and the clinical effect and its clinical significance were observed .Results Among these treated patients ,only 14 pa-tients appeared different degree of thoracic lumbar pain ,four patients lossed the fanterior flange height in small range ,the prognosis of the re-maining patients were good and didn＇t appear nerve root injury .Conclusion The clinical effect that used AF system in patients with thoraco-lumbar fixation is more prominent and the prognosis is better ,this treatment method make the restoration more accurately and has played a im-portant role in adjusting deformity and is deserved to be promoted .
